Customer Review: big pain no gain
Summary: 1 Stars
I, like some of the other reviewers, only got about 10 uses out of this battery before it quit holding a charge. By this I mean, it runs for 1 second and sings "come and find me"... which isn't as fun as usual because he will still be sitting at your feet. I used the roomba's service mode to run the wheels continuously to drain the battery down to zero. After a long day-long charge, it again rain for 1 second and stopped. No gain. Sad roomba.
The pain part is that it took forever to crack open my old APS battery as mine was very thoroughly sealed shut. I would recommend trying to open your battery before buying a kit like this to make sure you have one that is easy to open. Once open, the new battery kit does not fit quite right and required some force to get it in the old battery case. Then the new wires do not come with friction fittings or any other kind of connector.. just bare wires requiring soldering skills.. and a soldering iron.
Spend the extra $$ and get an irobot NiCD battery.. roomba just may not be compatible with the NiMH or I received a defective product. 2 stars if all you need is the triangular screwdriver and a blue and red doorstop.
